Sailor Mars

Named for Mars, the red planet, and indirectly for the Roman god of war, she is by far the best looking of the sailor scouts. She's known as Hino Rei when not in ass-kicking mode. If you've ever watched the english version, you know why she has such a short fuse for dealing with Serena; Serena's a whiny brat who runs away from anything more threatening than her talking cat.
